Strawberry plant named ‘DrisStrawTwentyThree’

ABSTRACT

A new and distinct variety of strawberry plant named ‘DrisStrawTwentyThree’ characterized by having very large, bi-conical fruit with medium sweetness and high yield is disclosed.

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawTwentyThree’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry varietydesignated ‘DrisStrawTwentyThree’ and botanically known asFragaria×ananassa. This new strawberry variety was discovered inHillsborough County, Fla. in December 2007 and originated from a crossbetween the proprietary female parent ‘1M16’ (unpatented) and theproprietary male parent ‘87K286’ (unpatented). A single plant wasselected for asexual propagation via tissue culture and vegetativecuttings in Shasta County, Calif. in 2007.

‘DrisStrawTwentyThree’ underwent further testing in Hillsborough County,Fla. for five years (2007-2011). The present invention has been found toretain its distinctive characteristics through successive asexualpropagations via stolons.

Plant Breeder's Rights for this variety have not been applied for.‘DrisStrawTwentyThree’ has not been made publicly available or sold morethan one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Hillsborough County, Fla.

-   -   1. High yield;    -   2. Very large, bi-conic shaped fruit; and    -   3. Medium sweetness.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

When ‘DrisStrawTwentyThree’ is compared to the proprietary female parent‘1M16’ (unpatented), ‘DrisStrawTwentyThree’ has higher yields and largerfruit than ‘1M16’.

When ‘DrisStrawTwentyThree’ is compared to the proprietary male parent‘87K286’ (unpatented), ‘DrisStrawTwentyThree’ has much higher yieldsthan. ‘87K286’.

When ‘DrisStrawTwentyThree’ is compared to the commercial variety‘Driscoll Sanibel’ (U.S. Plant Pat. No. 16,298), ‘DrisStrawTwentyThree’has a revolute terminal leaflet margin profile, a rounded terminalleaflet base, and stolons with absent or very weak anthocyanincoloration, while ‘Driscoll Sanibel’ has a flat terminal leaflet marginprofile, an obtuse terminal leaflet base, and stolons with stronganthocyanin coloration. Additionally, ‘DrisStrawTwentyThree’ hasbi-conical shaped fruit with a very broad band without achenes and acoarse texture on a plant that is not everbearing, while ‘DriscollSanibel’ has conical shaped fruit with a narrow band without achenes anda fine texture on a plant that is partially everbearing.
